Title: An improved method of and apparatus for continuously casting aluminium ingots
IPC: B22D11/14
Filed: 1961-10-04
Abstract: 936,775. Continuous casting-machines. REYNOLDS METALS CO. Oct. 4, 1961 [Dec. 16, 1960], No. 35792/61. Class 83 (1). A method of continuously casting aluminium ingot having throughout its length a purity continuously maintained at a substantially uniform level above the purity level of the molten feed metal comprises feeding molten metal into a mould, maintaining the metal molten in that part of the mould nearest the inlet, continuously withdrawing solidified metal from the outlet while causing the molten portion to flow rapidly over the interface between the molten and frozen metal and withdrawing from the mould as casting progresses, molten metal including metal which has flowed over the interface and contains a higher percentage of impurities than is present in the feed metal. Feed metal is fed in the form of pigs 16 on an endless chain 17 to a gas-heated crucible 19, from which it flows through a pipe 11 into a gas-heated mould 10. The melt is stirred at the interface by a graphite impeller 45 and molten metal overflows through a pipe 15 into a crucible 40. The solidified ingot is lowered by an hydraulic device 13 having clamps actuated by cylinders 63, 64, and lengths are cut off by a band saw 69.

Abstract: 1,164,444. Automatic voltage control. K.G. CORFIELD Ltd. (PRESTOLITE INTERNATIONAL CO). Sept.28, 1966 [Aug.24, 1965], No. 36206/65. Heading G3R. A voltage regulator for a D.C. generator which may be an alternator with a rectified output, includes a first switching transistor 25 which is connected in series with the field winding 13 of the generator and which is controlled by a second transistor 21 in dependence upon output voltage variations as detected by a voltage divider 14, 15, 16, and a Zener diode 20; this circuit operates in known manner to maintain a constant output voltage at terminals 11, 12 but in accordance with the invention a resistor is connected 28 between the point 19 and the collector of transistor 25. Thus, when the field current increases, the current through resistor 28 also increases, tending to reduce the potential across Zener diode 20 so as to retain it in its non-conducting state; when the diode 20 in fact becomes conductive, due to the increased output voltage at terminals 11 and 12 a current flows in the opposite direction through the resistor 28 to tend to increase the potential across the Zener diode so as to tend to retain it in its conducting state. The effect is thus to reduce the switching frequency of operation of the regulator, with a consequent reduction in the losses associated with the switching. A capacitor may be connected across the resistor 28, and the regulator may include a thermistor 18 to compensate for temperature variations.
